Not ready for prime time. Alpha quality. Sorry. Maybe later.
Fortunately, with Plasma 6, it's night and day from that, and even with 5.27 which Kubuntu 24.04 will ship, things are a lot more solid already.
That said, even the bleeding edge Plasma 6 (which has the most complete Wayland support and then some) doesn't work well in Wayland mode yet, it has plenty of issues with drag-n-drop, cursors, portals, much-hyped fractional scaling, and many other things (I still can't calibrate my drawing tablet display, for example). The overall experience beyond very basic features is flaky and unfinished.
I'm not even starting on implicit/explicit sync debate, that's a complete shitshow that can only be blamed on Wayland devs (regardless of Nvidia).
I've gone back and forth on wayland a few times now. It has both good and bad sides. Major functionality holes are finally getting plugged.
But the quality and stability of the compositors just isn't there yet compared to X11, and when leaving QT and GTK widget sets, almost nothing is fully baked. Presumably, things will get better in a few years.
